""Transparent Forging" allow each user's client to automatically determine who will generate the next block, so that they can then send their transactions to that node. This will also allow additional fees to be realized for immediate/priority transactions.

An equally important feature of Transparent Forging is an outstanding security feature of the protocol to temporarily reduce to zero the forging power of nodes who should generate the next block but don't. This transparent forging feature will prevent against even a 90% majority owner of all NXT branching out and forcing a fork. So if a node that has 90% of all Nxt, and doesn't generate a block when scheduled, the system will reduce its mining power to zero temporarily to prevent a bad fork from being forced. "

this is what I read in Nxt wiki... but can anyone elaborate why this really enhances the network security? I mean it´s kind of random who are my nodes at the moment so if I get unlucky
and have more then a bunch of nodes with bad intentions (double-spending or w/e) they could deliberately miss out on generating a scheduled block
and getting away with it.

Or is this not a problem in reality? Sorry if this is a really stupid question, but I´m really unexperencied with this  proof-of-stake / forging as underlying security for a coin.
